As for time? My 8×8″ dish took about 40 minutes. I suspect a 9×13″ would take 20 minutes and give a more solid bar. Whichever way, score slices while warm with a sharp knife, then let cool completely before lifting out. They will firm up as they cool.

Notes:

They can be made vegan as well, use vegan margarine or coconut oil and agave nectar. How many bars depends on the size of pan used.
